We have reports that there was an earthquake near Red Deer. At this point, we can't confirm whether the power outage was related to this and continue to work with @AltaLink on the investigation. #Alberta— FortisAlberta (@FortisAlberta) March 4, 2019
Historically, this is one of the largest recorded earthquakes to ever strike Alberta.
The only stronger earthquake was a magnitude-4.8 tremor that shook Jasper, right on the British Columbia border, 38 years ago.
Another magnitude-4.6 earthquake was measured in Lethbridge in 2003.
According to Earthquakes Canada, however, this is the largest recorded earthquake for this specific region of Alberta.
An official cause for the earthquake hasn’t been provided, but the speculation from many is that it was caused by fracking.
